| |
Hi,
I have an old Logitech webcam, with USB IDs 046d:08b3. When I try to use this camera now, I see this error in the dmesg log:
[ 2883.852464] pwc: isoc_init() submit_urb 0 failed with error -28
This error is apparently ENOSPC, which made me suspect that I was trying to use a mode that would require compression. However, when I tried using setpwc to configure the camera's options I received more errors: $ setpwc -c 3 setpwc v1.3, (C) 2003-2006 by folkert@vanheusden.com Error while doing ioctl VIDIOCPWCSCQUAL: Inappropriate ioctl for device
Has the kernel-to-userspace interface for PWC devices changed? Because how else could this IOCTL be "inappropriate"? Is there an alternative to setpwc, please?
Thanks, Chris
